COVID-19 not Man-Made, Comparative genetic engineering Study Concludes

No, the coronavirus wasn’t made in a lab. A genetic analysis shows it’s from nature

The coronavirus pandemic circling the globe is caused by a natural virus, not one made in a lab, a new study says.

The virus’s genetic makeup reveals that SARS-CoV-2 isn’t a mishmash of known viruses, as might be expected if it were human-made. And it has unusual features that have only recently been identified in scaly anteaters called pangolins, evidence that the virus came from nature, Kristian Andersen and his colleagues report March 17 in Nature Medicine.

What is genetic engineering?

  • Genetic engineering, sometimes called genetic modification, is the process of altering the DNA? in an organism’s genome?.
  • This may mean changing one base pair? (A-T or C-G), deleting a whole region of DNA, or introducing an additional copy of a gene?.
  • It may also mean extracting DNA from another organism’s genome and combining it with the DNA of that individual.
  • Genetic engineering is used by scientists to enhance or modify the characteristics of an individual organism.
  • Genetic engineering can be applied to any organism, from a virus? to a sheep.
  • For example, genetic engineering can be used to produce plants that have a higher nutritional value or can tolerate exposure to herbicides.

How does genetic engineering work?

  • To help explain the process of genetic engineering we have taken the example of insulin, a protein? that helps regulate the sugar levels in our blood.
  • Normally insulin? is produced in the pancreas?, but in people with type 1 diabetes? there is a problem with insulin production.
  • People with diabetes therefore have to inject insulin to control their blood sugar levels.
  • Genetic engineering has been used to produce a type of insulin, very similar to our own, from yeast and bacteria? like E. coli?.
  • This genetically modified insulin, ‘Humulin’ was licensed for human use in 1982.
